Abstract

PROBLEM TO BE SOLVED: To establish a windmill method which matches a method for offshore power generation on the wide ocean, especially floating body type offshore power generation, which is important.SOLUTION: Because a self-stabilizing vertical axis windmill is employed that flexibly combines a horizontal wing and a vertical wing so as to be freely rotatable, no unbalanced load is generated unlike the horizontal-axis windmill and the need for considering wind directions is eliminated, so that it becomes possible to develop a system which does not create adverse effect on the windmill support. In addition, when three windmills are built using a flexible link mechanism in order to form a triangle and then multiplexed based on this shape by the same method, stable operation can be executed even in the wind farm with a large number of many windmills. In addition, collaboration with fishery and early launch of the floating wind farm can be performed to effectively cope with food crisis in future.

Description

  The present invention relates to wind power generation, and more particularly to floating offshore wind power generation used on a deep sea where a self-stabilizing vertical axis wind turbine is installed.

In recent years, power generation that does not use oil or coal has been attracting attention as part of measures to deplete petroleum resources and global warming.
In particular, since the Fukushima nuclear power plant accident caused by the Great East Japan Earthquake last year, attention has been focused on renewable energy other than nuclear power, oil, and coal.
Among them, solar power generation and wind power generation are playing an important role.

  With regard to solar power generation, small-scale power generation installed on the roof of each household has an advantage because the roof space can be used effectively. However, in the case of large-scale solar power generation, it is necessary to install solar panels with a large area. In this case, however, green areas such as forests and fields will be crushed instead, from the viewpoint of measures against global warming. Would go backwards, which is undesirable. That is, in the case of photovoltaic power generation, for example, if 100 energy is obtained, the green space corresponding to 100 is lost. For example, even if the land is currently idle, in the event of a food crisis due to a global population explosion that will come in the near future, the land needs to be used for immediate food production, In that case, the solar panel will be removed, which is not suitable for permanent energy measures.

On the other hand, in the case of wind power generation, for example, as a result of absorbing solar energy in the wide ocean, strong winds are generated and come to Japan, compared to solar power generation from the viewpoint of energy collection, accumulation and integration There are far greater benefits. In other words, since the heat energy accumulated in the ocean is much larger than the area of Japan, there is almost no green space used for wind power generation.
Of course, a facility for processing the electric power sent from the offshore power generation facility by the submarine cable is necessary on land, but a large area is not necessary.

As for wind power generation, horizontal axis wind turbines currently occupy the mainstream, but most of them are installed on land, and there are private houses nearby, so installation is not progressing due to problems such as noise. There are also regions. Japan, for example, is just an example.
In the case of a horizontal axis wind turbine, the load around the wind turbine axis is uneven, and it is very difficult to maintain verticality.Furthermore, it is necessary to always face the wind, so it can respond to rapidly changing wind directions. Is very difficult.
This is especially true for offshore power generation, especially in the case of deep seas of 100m or more, which occupies 60% or more of the entire earth. There are high hurdles and it is difficult to realize.

  In the case of a vertical axis windmill, the center of rotation of the windmill and the center of the windmill mounting tower completely coincide with each other.

  In this way, offshore wind power generation is very important for the country surrounded by the sea, and there is no doubt that it will become mainstream from now on. Installation of floating wind power generation is a necessary condition when there is water depth, but such horizontal axis wind turbines are not practically used anywhere in the world. In particular, in areas where there is water depth and the wind direction changes rapidly, vertical axis wind turbines that do not care about the wind direction are effective, and recently, a lot of attention has been tried around the world. No promising method has been reported.

  Consider efficient use of vertical axis wind turbines under various wind conditions and effective protection measures.

Problem 1 is to prevent the windmill from rotating and destroying it under any strong wind.
Generally, when a strong wind such as a typhoon blows, a measure is taken to forcibly stop the windmill by a brake or the like to prevent the windmill from being damaged. In this case, a powerful braking system is required for the energy of a powerful typhoon, which causes problems such as the necessity of improving the strength of the windmill and cost increase. Furthermore, when a strong turbulence such as a typhoon is swirling, a specific windmill blade that is stopped may receive a large force in a concentrated manner, and there is a risk that destruction is concentrated. If it is rotating, such a force is dispersed and averaged, so it is difficult to cause a problem.
Furthermore, if the windmill is stopped under a strong wind, the energy of a powerful typhoon will be wasted.

Issue 2 is to maintain the verticality of the floating structure under any wind conditions.
Whether it is a horizontal axis wind turbine or a vertical axis wind turbine, if the wind turbine axis is tilted by repeated strong winds and waves from typhoons, hurricanes, etc. It is possible and causes troubles. Under any wind conditions, it is essential to ensure the verticality of the windmill axis and calm down the vertical movement.

Issue 3 is to not adversely affect marine life in the surrounding waters where offshore wind turbines are installed.
In order to perform large-scale power generation on the ocean, it is necessary to install a large number of windmills. In this case, the marine organisms such as marine plants and fishery products should not be adversely affected in the sea area where they are installed. Therefore, it is essential to not cut off sunlight or tidal currents. This makes it possible to collaborate with fisheries and to deploy offshore wind power generation in a wide area in a short time.

Issue 4 is to be as maintenance-free as possible with as few troubles as possible.
Offshore wind power generation requires long-time unmanned operation in deep waters away from land, but maintenance-free is an important condition for that. However, most of the wind turbines currently in use use a generator with a speed increasing gear for both the horizontal axis wind turbine and the vertical axis wind turbine. This type of generator is indispensable for regular maintenance due to gear wear. This has problems such as periodic interruption of power generation and maintenance costs.
In order to cover a considerable amount of power generation by offshore wind power generation, the above problems 1 to 4 need to be completely solved.

Hereinafter, the present invention will be described with reference to embodiments shown in the drawings, but the present invention is not limited to the embodiments shown in the drawings.
As the name suggests, the present invention will first describe measures for achieving self-stabilization of a vertical axis wind turbine.

FIG. 1 is a perspective view of a self-stabilizing vertical axis wind turbine.
FIG. 2 is a side view of FIG. 1 in a state of rotating at a low speed. However, since the centrifugal force is small, the vertical blade is held by the vertical blade angle holding portion.
FIG. 3 is also a side view, but shows a state in which the vertical blades are flipped upward by a centrifugal force of high-speed rotation.
FIG. 4 represents the state of the vertical wing of FIGS. 2 and 3 at the same time so that the concept of the present invention can be easily understood.
Basically, a windmill rotation holding portion 5 is installed at the upper end of the windmill shaft 4, and a plurality of horizontal blades 3 are fixed to the windmill rotation holding portion 5.
At the blade tip of the horizontal blade 3, a rotation holding unit 2 for rotatably connecting the vertical blade 1 is installed in the tangential direction of the rotation locus on the rotation surface of the horizontal blade 3.
The coupling portion of the rotation holding portion 2 is installed at a substantially intermediate position of the vertical blade 1.
Thereby, although the vertical blade 1 is rotatably installed, it is normally held at a predetermined angle by the angle holding unit 32.
The vertical blade 1 is rotated by an external force such as a centrifugal force and a strong gust due to the high-speed rotation of the vertical blade 1, and is held at a position where the resultant force of gravity, centrifugal force, wind force and the like is balanced.

These will be described with reference to FIGS.
First, the balance of the horizontal blade 3 will be described with reference to FIG.
When the wind turbine is stopped or rotating at a low speed, the horizontal wing 3 hangs a little like the main wing of the jumbo machine because of the weight of the vertical wing 1 and the horizontal wing 3 itself as shown in FIG.
This seems to be unstable at first glance, but, like Yajirobe's movement, is warped and stable.
In order to realize this, it is desirable that the horizontal wing 3 is not a very rigid body, but is a little soft and has a softness like a whip with bending.
When the wind turbine rotates at a high speed, the centrifugal force acting on the vertical blade 1 becomes larger than the gravity, so that the downward sag is reduced and the wind turbine becomes almost horizontal. When the centrifugal force is further increased, the horizontal blade 3 is lifted upward.
That is, as shown in FIGS. 6 to 8, the vertical wings 1 gradually rotate from the initial holding angle and jump up.

Next, the balance of the vertical blade 1 will be described with reference to FIG.
As an initial condition, the length of the lower half from the rotating part of the vertical blade 1 is longer than the length of the upper half.
First, considering the balance in the absence of wind from FIG. 7, since the center of gravity of the vertical blade 1 is located below the center of rotation, only the gravity acts in the direction of pushing down the vertical blade 1, and the blade is stable.
Next, as shown in FIG. 8, when rotating, the force acting on the center of gravity of the vertical wing is centrifugal force in addition to gravity, and the resultant force is exerted. As a result, the centrifugal force is determined by the number of revolutions, so that it stabilizes at a position balanced by the resultant force with gravity. However, as the number of revolutions increases, the centrifugal force also increases and the vertical blades jump up step by step.

The state is shown below. Calculation formula 1 in FIG. 9 represents the relationship between the wind turbine rotation speed and the vertical blade jump angle with the wind turbine radius as a parameter. Table 1 summarizes the calculation results.
Graph 1 in FIG. 10 is a graph of the above result.
For example, when the rotational speed is 3 revolutions per minute, the look-up angle of the blade with a windmill radius of 3 m is 1.7 °, but when the windmill radius is 30 m, the flip-up angle is 16.8 °.
Similarly, when the rotational speed is 10 revolutions per minute, the wing angle of the blade with the windmill radius of 3 m is 18.6 °, but when the windmill radius is 30 m, the rake angle is 73.4 °.
Further, when the rotational speed is 30 revolutions per minute, the jump angle of the blade with the windmill radius of 3 m is 71.7 °, but when the windmill radius is 30 m, the lift angle is 88.1 °, Nearly level.
This method seems to have a good effect on a small windmill with a small windmill radius, but it is also considered that the effect of jumping up is too effective on a large windmill.

FIG. 11 is a perspective view when the vertical blade 1 is installed at a position offset from the rotation holding unit 2 installed at the blade tip of the horizontal blade 1, which is a modified type of the present invention.
FIG. 12 is a side view showing a state in which the vertical blade is held at a predetermined angle by gravity due to low-speed rotation.
FIG. 13 is a side view showing a state in which it is jumped upward by a centrifugal force of high speed rotation.
FIG. 14 shows the states of FIGS.
The merit of this type is that the rotational moment of the vertical wing 1 in the downward direction due to gravity increases by offsetting, and it becomes possible for the vertical wing 1 to maintain the initial angle in the low rotation region. It is possible to improve the energy utilization efficiency in many low wind speed regions.

In FIG. 15, the centrifugal force is small with respect to gravity, and the extension line of the resultant force is stable because the force in the direction of pushing down the vertical blades on the outer peripheral side of the offset rotation center works.
FIG. 16 shows a state in which the centrifugal force increases and the extension line of the resultant force passes just above the center of rotation.
FIG. 17 shows a state in which the centrifugal force is further increased and the extension line of the resultant force passes below the center of rotation and the vertical wing is flipped up.

The wind power can be understood by looking at the diagram in FIG.
When the vertical wing 1 is located in the same direction as the wind direction, the vertical wing 1 moves in the direction in which it is raised.
On the other hand, when positioned in the opposite direction, the vertical wing 1 moves in the direction in which it is pushed down.
That is, a force that is flipped up or pushed down while the vertical wing 1 is rotated once is exerted.

In this case, since it does not move suddenly due to the inertial mass of the vertical blade 1 and the inertia of the rotation holding part 2, this is not a problem. If the inertia at the time of lifting is smaller than the inertia at the time of pushing down, it is possible to prevent the wing from jumping up quickly and excessively increasing the number of revolutions and damaging the wing.
In this way, by making the vertical blade 1 rotatable, it becomes possible to prevent the windmill from rotating excessively during a typhoon or the like, or being destroyed by excessive force due to gusts or turbulence. .
2 to 8 and 12 to 17 show a state in which the angle of the vertical blade 1 is changed.

FIG. 18 shows that the linear guide 35 and the cylinder 36 are arranged on the horizontal wing in order to give the damper characteristic to FIG. 1 which is the first invention. It is connected to the wing 1.
FIG. 19 shows a state where the cylinder 36 of FIG. 18 is contracted and the vertical blade 1 is jumped up by the arm 34.

FIG. 20 shows a basic configuration of the invention shown in FIG. 1, in which a linear guide 35 and a cylinder 36 are arranged under the horizontal wing, and a vertical wing 1 is connected via a slider and a cylinder on the linear guide, and a connecting arm 34. It is combined with.
FIG. 21 shows a state where the cylinder 36 in FIG. 20 is contracted and the vertical blade 1 is jumped up by the arm 34.

  FIG. 22 shows the second invention in FIG. 2, in order to give the damper characteristics, a cylinder 36 is arranged on the horizontal wing, and the tip of the rotatable horizontal wing 11 is connected to the cylinder via a rotatable joint 37. Is. The cylinder 36 is installed in the rotation holding portion by a fixed portion that rotatably holds a part of the cylinder.

23 has a linear guide 35 and a cylinder 36 arranged under the horizontal wing in order to give the damper characteristics to FIG. 2 which is the second invention, and the horizontal wing through the slider and cylinder on the linear guide and the connecting arm 34. 11.

  24, in order to give the damper characteristic to FIG. 2 which is the second invention, a linear guide 35 and a cylinder 36 are arranged under the horizontal wing, and the horizontal wing is passed through the slider and cylinder on the linear guide and the guide groove 38. 11.

FIG. 25 shows a second invention in which a linear guide 35 and a cylinder 36 are arranged under the horizontal wings to provide the damper characteristics in FIG. 11. The following fluid system is installed in the cylinder for the purpose of making a difference in damping characteristics when the cylinder extends and contracts. That is, in order to facilitate the vertical wing jumping, in the cylinder arrangement shown in FIG. 25, the direction in which the vertical wing jumps is the direction in which the cylinder contracts, so the fluid can easily flow out from the cylinder. Install in the direction, and install an orifice with a large diameter and a small fluid resistance. Furthermore, since the direction in which the vertical wing returns is the direction in which the cylinder extends, an orifice with a small inner diameter and a large fluid resistance is installed in the check valve installed in the inflow direction so that the outflow of fluid from the cylinder is difficult. . Both orifices are connected to a fluid reservoir 43.
In the case where the fluid is air, the fluid reservoir 43 is not necessary and may be simply opened to the atmosphere.
The system in FIG. 26 may be exactly the same as in FIG.

FIG. 27 is a document for explaining in detail what has been described with reference to FIGS.
The graph in (1) shows the vertical blade jump time constant and return time constant due to the difference in damping characteristics. The horizontal axis of the graph shows the elapsed time, and the vertical axis shows the vertical wing jump angle. Since the time constant at the time of jumping up from the graph is small, it means that the jumping up proceeds within a short time, and when it returns, it only moves slowly.
The graph in (2) is a material for explaining the difference in vertical blade deflection angle depending on the presence or absence of selective damping characteristics. This graph shows how the wing behaves when wind hits a vertical wing with a certain swing angle due to the centrifugal force of rotation. The horizontal axis represents the change in angle with the passage of time of the wing angle when the wind direction is 0 degree. The vertical axis represents the swing angle of the vertical wing. In the graph, 0, 2π, 4π, etc. in the same direction as the wind indicate maximum values, π, 3π, 5π, etc. in the opposite direction indicate minimum values, 0.5π, 1. 5π, 2.5π, etc. indicate zero. This is a so-called COS curve.
(3) The state where the selective damping characteristic is active is a graph represented by a dotted line, and it can be seen that the swing width of the vertical blade is clearly reduced. By changing the damping characteristics, the amplitude can be changed greatly.

FIG. 28 shows the damping system of FIG. 23 in which the connecting portion of the movable horizontal blade 11 and the vertical blade 1 is replaced with a rotating shaft 66. This is adopted to prevent the vertical wing from being destroyed by a large centrifugal force caused by high-speed rotation.
FIG. 29 is the addition of a rotation axis for the same purpose as in FIG. 28 applied to FIG.
FIG. 30 shows a fixing metal 67 made of a spring material for maintaining the rotation angle at a predetermined value in FIGS.
FIG. 31 is obtained by replacing the rotating shaft 66 and the fixing bracket 67 of FIG. 30 with a spring plate 68. If an appropriate material is found as the material of the spring plate 68, it is expected that merits such as cost reduction and fluid resistance reduction will be achieved by reducing the number of parts.

FIG. 32 is a perspective view of an arc-shaped vertical wing 1 which is a modification of the present invention, and FIG. 33 is a side view.
FIG. 34 is a side view showing a state in which the arc-shaped vertical blade 1 is climbing up by high-speed rotation.
FIG. 35 is a side view comparing the movement of the arcuate vertical blade 1 during low-speed rotation and high-speed rotation by combining FIGS. 33 and 34.
36 is obtained by replacing the vertical wing 1 of the system of FIG.
As shown in the figure, the arc-shaped vertical blade 19 can have a large arc radius due to the centrifugal force accompanying the rotation at that time. If you can find a material with such elasticity, you will be able to complete a very good windmill.

FIG. 37 is a detailed cross-sectional view of the windmill rotation holding unit 5 and shows main components. Reference numeral 6 denotes a coupling portion between the wind turbine shaft 4 and the rotation holding unit 7, which is responsible for receiving the weight of the entire wind turbine and controlling the attitude of the rotation holding unit. The rotation mount 9 is engaged with the rotation holding part 7 by means of sliding bearings 8 and 10. The horizontal wing 3 is fixed to the rotary mount 9.
Figure 38 shows the gearless installed in the windmill rotation holding part. direct. It is detailed sectional drawing of a drive system generator.
It is sectional drawing in the state by which the coil 15 is arrange | positioned between the 12 and 13 pair magnets in the windmill rotation holding | maintenance part 5 of FIG. Reference numeral 14 denotes a U-shaped structure for coupling the pair magnets 12 and 13.
The feature of this system is that the power generation element is arranged in the immediate vicinity of the sliding bearing 8, so that the number of parts is small, the structure is simple, the position is not displaced, and stable operation can be realized at low cost for a long time. It is possible. That is, there is a possibility that maintenance-free can be realized.

FIG. 139 shows the gearless. direct. The circuit for electric power generation used for a drive system generator is shown. The output from the coil 15 is guided to the relay 26-.
The relay 26 has three contact points, the contact point 2 is open, the circuit is cut off at the time of ultra-low speed rotation when there is no wind or light wind, the contact point 1 is connected to the battery 28 from the rectifier 27, and the contact point 3 is connected to the coil 15. It is connected like a short circuit, and can work as an electric brake during ultra high speed rotation such as during a typhoon.

By switching on and off of the relay 26, signals of the anemometer input 31 and the wind turbine rotation speed input 30 can be processed by the control unit 29 so that the power generation in the best state can be performed.
The basic idea is to open the relay 26 if there is no wind, connect the relay 26 to the rectifier 27 if the wind blows properly, charge the capacitor 28, and short the coil 15 if the wind is too strong. Even when a strong wind is blowing, it is charged when it can be recharged as much as possible, and when it is over-rotated and dangerous, the brake is run to prevent the windmill from being destroyed.

FIG. 40 is a cross-sectional view of a state in which the reinforcing structure 17 for preventing the horizontal blade 3 from dripping is installed on the horizontal blade 3.
FIG. 41 is a perspective view showing a state in which the basic pre-starter 16 is installed on the horizontal blade 3.
The pre-starter 16 is installed near the center of rotation on the horizontal wing 3. As a basic idea, it is necessary to select a shape that does not have a large fluid resistance so as not to disturb the rotation during rotation.
FIG. 42 is a perspective view showing a state where FIGS. 40 and 41 are docked.
The cover 18 is selected so that the fluid resistance during rotation is as small as possible, but may be integrated with the reinforcing structure 17 in some cases.
FIG. 43 shows a structure in which the movable plate 44 is coupled to the reinforcing structure 17 for preventing the horizontal wing 3 of FIG. During low rotation, the movable plate 44 rises obliquely as shown in FIG. 43, but during high speed rotation, the movable plate 44 becomes horizontal to reduce fluid resistance. The movable plate 44 may be operated by a spring or may be controlled electrically.
FIG. 44 shows that the movable plate 44 is in a horizontal state during high-speed rotation.

45 is a perspective view showing a state in which two substantially L-shaped vertical blades 1 are arranged in a mirror image relationship with respect to the intersection of the vertical shaft 4 and the horizontal blade 3, and FIG. FIG. At first glance, this seems anomalous and not very beneficial, but it has its own characteristics. This will be described with reference to FIG.
FIG. 47B shows the wind direction. As will be described with reference to FIG. 37A, the description will be made by paying attention to the forces acting on the bearings 8 and 10 of the windmill rotation holding portion 5 in FIG.
First, the force due to gravity works equally in the direction of pressing the bearing, as can be seen from the figure.
Since the centrifugal force is the one that pushes down and the other is in the direction of pulling up, the partial load will work, but this force is always the same and steady as long as the number of rotations is the same, and does not cause a problem. .
Since the force due to the wind is in the direction in which one is pushed down and the other is also pushed in, the load on the bearings 8 and 10 seems to be very small.
Normally, the force of this wind force is unstable, and the state changes during one rotation, so the problem of large vibration during rotation is common to vertical axis wind turbines, but this is reduced in the case of the L type. The

FIG. 48 is a perspective view showing a state where three pairs of the L-shaped vertical blades 1 shown in FIG. 45 are arranged.
In this case, all three parameters of gravity, centrifugal force, and wind force are balanced in the above description. In actual prototypes, very stable rotation has been demonstrated even in strong winds.

FIG. 54 shows a state in which the solar panel 46 is docked in the first invention and the second invention. Such a combination is very advantageous for small and medium-sized direct axis wind turbines. As an application field, as shown in FIG. 55, it is possible to arrange them at regular intervals in a single line in the median strip of an expressway, or arrange them at regular intervals in a line along a railroad track.
As shown in FIGS. 56 and 57, it may be installed on the roof of a private house.

FIG. 58 (A) is a perspective view showing a buoyancy structure in which a self-stabilizing vertical axis wind power generation unit is incorporated. A posture stabilizing ballast 23 is installed at the lower part of the main float 21 via the coupling structure 22, the wind turbine shaft 4 is installed at the upper part of the main float 21, and the wind turbine is installed at the upper end thereof.
FIG. 59 is a diagram showing the water level adjustment of the buoyancy structure. By injecting a low specific gravity material into the coupling structure under the float by an external signal, the water is replaced with a light material, so that the buoyancy structure is lightened and the buoyancy structure is lifted up.
FIG. 59 (A) is the most elevated in a normal state.
FIG. 59 (B) is used when the wave is high in a state where it is slightly sinking.
FIG. 59 (C) is used when the main float part is also submerged and is used in the case of intense waves or high tsunamis. However, since the main float is also submerged, it is not easily affected by waves and the windmill axis is intense. It is possible to suppress vertical movement.
The external signal is a sensor signal such as a water level, a wave amplitude, a vertical movement width of a buoyancy structure, or a danger signal based on a typhoon or tsunami from an external control center.

Since this buoyancy structure can maintain a stable posture against high waves, a tidal power generation unit and a wave power generation unit can be provided side by side.
FIG. 60 shows a state where two propeller-equipped tidal current power generation units are installed in the buoyancy structure.
FIG. 61 shows a state where two wave power generation units are installed in the buoyancy structure.

  62 is a perspective view of a buoyancy structure system in which two buoyancy structures 22 are rotatably coupled by two horizontal struts 24 to form a parallelogram, and FIG. 63 is a side view. Since this system is rotatably coupled so as to form a parallelogram by two horizontal columns 24, even if one buoyancy structure 22 is inclined by a strong wave or the like, the other buoyancy structure 22 There is no problem because it is held.

FIG. 64 shows that the two buoyancy structures 22 can be rotated by two buoyancy structures 22 arranged at positions where they form an isosceles triangle with the two buoyancy structures 22, respectively, by two horizontal struts 24. It is a perspective view in the state where it is connected to and is going to form a triangle. The three buoyancy structures 22 are connected by two horizontal struts 24 each.
FIG. 65 is a perspective view showing a state in which the triangular combination is completed from the state of FIG. 64 described above.

FIG. 66 shows the results of experiments showing the perpendicularity maintaining characteristics of the buoyancy structure against the vertical movement of the waves.
Data was obtained by changing the buoyancy size of the buoyancy structure in three stages.
(1) Weight-3 buoyancy = 2 × (Weight-2 buoyancy) = 2 × [1.5 × (Weight-1 buoyancy)]
(2) Tilt angle of the floating structure relative to the tilt angle of the horizontal support (parameter = buoyancy)
(3) Result → For example, for the maximum tilt angle of 11.2 ° of horizontal struts * Weight-1 tilt angle = 5 °
* Weight-2 tilt angle = 4.3 °
* Weight-3 tilt angle = 1.7 °
When calculated, the attenuation effect of Weight-3 = 1.7 ° / 11.2 ° = 0.15 = 15%
That is, Weight-3 was able to suppress the inclination of the floating structure to 15%.
If the buoyancy of the floating structure is further increased, the damping effect may be further increased.
The graph in FIG. 67 represents the attenuation effect.
This actually proves the effect of the present invention.

It is possible to arrange a fish cage 25 described later near the center of the triangle.
FIG. 68 shows a state where the sacrifice 25 is arranged at the center of the triangular coupled buoyancy structure.

Floating wind power generation in deep water is the most targeted field of the present invention, and is expected to be able to start up and operate at an early stage through collaboration with fisheries, etc., and to supply a considerable proportion of future power requirements. Is done.
Furthermore, according to the present invention, the wind turbine is a vertical axis wind turbine that does not care about the wind direction, and since the vertical blades can be bent by rotation, it is possible to avoid damage due to excessive force such as gusts and high speed rotation. .
This makes it possible to operate stably for a long time without a person.

  For example, a large number of windmills can be installed if they are installed at regular intervals in a vast and long space such as an expressway or a bullet train, and it is possible to cover a certain proportion of the required power. In this case, the noise problem is not a problem in both cases, so it is not so difficult to obtain the understanding of the local residents and others concerned about the installation.

  Furthermore, when looking overseas, desertification is progressing in various places due to global warming phenomenon, but a huge number of windmills are installed in this area, and the groundwater is directly pumped by taking advantage of the characteristics of the vertical axis windmill. I can do it. Alternatively, if the groundwater can be pumped up by the electric power generated by the vertical axis wind turbine, or if water can be generated and greening can be promoted, changing the desert to green space should not be a dream, and the inventor will I am willing to work hard so that I won't end it with a dream.
